WRENCH.

EJPECIFIGATION forming part of Letters Patent No. 350,602, dated October12, 1886.

Application filed March El, 1886.

To aZZ whom it may concern.-

Be it known that I, WILLIAM J. PULLIAM, of Chico, county of Butte, andState of California, have invented an Improvement in Wrenches; and Ihereby declare the following to be a full, clear, and exact descriptionthereof.

My in vention relates to the class of wrenches, and particularly to anew and useful wrench for adjusting the nuts on the teeth of thrash IOlug-cylinders.

My invention consists in a short stock for entering the cylinder, ahandled shank pivoted in said stock and projecting outwardly between thecylinder-bars, a socketed piece or r jaw pivoted in the stock forengaging the not from within. gears by which the rotation of the shankis transmitted to thesocketed piece I or jaw, a clamp on the stock forengaging one of the cylinder-bars and holding the stock steady. and ajawor holder on the shank for engaging the tooth and keeping it fromturning, all of which I shall hereinafter fully describe.

The object of my invention is to provide a or loosening the nuts, bywhich the teeth of a thrashingcylinder are secured to the bars withouthaving to reverse the cylinder.

Referring to the accompanying drawings,

Figure l is a perspective view of my wrench.

Fig. 2 is a View showing its application.

A is the stock, consisting of a short box small enough to enter betweenthe bars of the cylinder. w

3 5 B is a shank having a handle, I), and pivoted in the stock, wherebyit may be rotated. In the stock is also pivoted or journaled the nut-vengaging jaw, here shown as a socketed piece, 0, which lies parallelwith the shank, as shown.

0 Upon the stem of this jaw G, and housed in the stock A, is a gear orpinion, 0, which engages with another gear or pinion, b,'upon the mainshank B, whereby power is transmitted from said shank torotate thesocketed piece 4 5 or jaw.

Upon the inner side or bottom of the stock A is a clamp-arm, D, havingabent or hooked point, d. The clamp-arm is fixed by a small set-screw, d,and may be adjusted longitudi- "the teeth are secured.

of holes, (1", in its body, with any of which the set screw may engage.

Fitted loosely upon the shank B is a forked jaw orholder, E, fromthehubof which an arm,

6, extends toward. and is adapted to enter a socket or hole, a, in thestock A. g

The use of my wrench is seenin Fig. 2. F are the bars of athrashing-cylinder. G are the teeth, the threaded shanks of which passthrough the bars, and Hare the nuts by which WVith the ordinary wrenchthe operation of fitting and tightening up the teeth or of removing themis rather long and tedious. Thetooth is first put through its seat inthe bar, and is then struck with a hammer to drive it home properly.Then the entire cylinder must be reversed or turned half-way around inorder to permit the wrench to pass through and operate on the inside ofthe then opposite side of the cylinder, in order to adjust and tightenup the nut on the inwardly-projecting shank of the tooth. When this iscompleted, the cylinder must be turned forward again and the next toothinserted, as before. In using my wrench this constant reversal of thecylinder is avoided, and the tooth may he fitted, driven in, and its nutadjusted and tightened up without moving the cylinder at all. As willbeseen, the stock of the wrench is passed through between the bars of thecyl- 8o inder, and its socketed piece or jaw O fits over the nut. Theclamp-arm D then engages with its hooked or bent end'one of the bars,either above or below, according to the direction in which it is turned.This prevents the stock from moving, and by reason of the longitudinaladjustment of said clamp-arm it may be fitted to various cylindershaving different spaces between their bars. The forked jaw or holder Eslips up over the sides of the tooth 0 and prevents said tooth fromturning, and saidjaw or holder is itself held firmly by the engagementof its arm c with the hole' a in the stock. The sliding movementof the forked holder "enables it to be readily fitted and ad- 5 justedto various lengths and positions. Every part being now fixed the handleI) is turned, whereby rotation is imparted to the socketed piece or jawG, and the nut is set up or loosened, as the case may be. It will thusbe seen that I00 the tooth can be driven in and its nut set up withouthaving to move the cylinder.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. I11 a wrench for adjusting the nuts on the teeth of athrashing-cylinder, the combination of the stock A, for entering thecylinder, the handled shank B, pivoted in the'stoek and extendingoutwardly between the cylinder-bars, the nut-engaging piece or jaw O,pivoted in the stock, the gears between said jaw and the shank B andhoused in the stock, a clamp on the stock for engaging the bars of thecylinder and holding said stock steady, and a jaw on the shank B forengaging and holding the cylinder-tooth, substantially as described.

2. In a wrench for adjusting the nuts on the teeth of athrashing-eylinder, the combination of the stock A, for entering thecylinder, the handled shank B, pivoted in the stock and extendingoutwardly between the cylinder-bars, the nut-engaging piece or jaw O,pivoted in the stock, gearing, between theshank and said jaw, and thelongitudinally adjustable clamparl n D. secured to the stock forengaging the eylinderbars, substantially as and for the purpose hereindescribed.

3. In awrench for adjusting the nuts on the teeth of at-hrashing-eylinder, the combination of the stock A, having a socket orhole, a, the

handled shank B, pivoted in the stock, the nut-engaging piece or jaw G,p voted in the stock, gearing between said jaw and the shank B, and theadjustable forked jaw or holder E, fitted on the shank for engaging thecylindertooth, and having an arm, 6, entering the hole a in the stock,substantially as herein described.

4. A wrench for adjusting the nuts on the teeth of a thrashing-cylinder,comprising the stock A, for entering the cylinder, thehandled shank B.pivoted in the stock and extending outwardly between the cylinder-bars,the sock eted piece or jaw G, pivoted in the stock and engaging the nutfrom within, the pinions or gears b c in the stock and upon the shank Band jaw C, respectively, the longitudina lyadjustable clamp arm D on thestock for engaging the cylinder-bars, and the adjustable forked jaw orholder E on the shank B, for engaging the cylinder-tooth, and having anarm, 6, engaging a socket or hole in the stock, all arranged and adaptedto operate substantially as herein described.

In witness whereof I have hereunto setmy hand.
